One possible plotline could be how they manage to keep their relationship a secret from their friends and classmates. They might have to come up with elaborate excuses for why they're spending time together or being overly protective of each other in a way that doesn't seem too obvious.
A third plotline could be the discovery of their relationship by an unexpected character. Maybe a villain somehow finds out and tries to use it against them. This would lead to a whole new set of challenges as they not only have to deal with the fallout within their own circle but also protect themselves from the villain's schemes.
Another plotline could involve the internal struggle of one or both of them. For example, Izuku might worry about how their relationship could affect their hero training and goals, while Katsuki could struggle with his pride and how to show his softer side in this secret relationship. It could be a really interesting exploration of their characters.
Ochaco Uraraka could be a main supporting character. She's Izuku's friend and might notice some changes in his behavior due to the secret relationship. Her reactions and how she might accidentally get closer to uncovering the secret could add a lot of drama.
A great way to develop their relationship is through shared traumas. Maybe they both had a difficult experience during a villain attack. They could open up to each other about their fears and insecurities during that time. This vulnerability would bring them closer together. Additionally, they could participate in a hero competition together. As they face tough opponents, they encourage each other and celebrate their victories, which deepens their bond.
One idea could be that female Izuku, with her determination, constantly challenges Katsuki in hero training. Their rivalry turns into a deeper understanding and they start to support each other more. For example, in a joint mission against a powerful villain, they realize each other's strengths and weaknesses and work together seamlessly, which then leads to a new level of friendship that could potentially turn into something more romantic.
One common theme is the transformation of their relationship from rivals to lovers. They start off being competitive and then gradually see each other in a new light. Another theme is the exploration of their individual growth as they are in a relationship. They learn from each other and become better versions of themselves.
They might create false stories or alibis. Say if they go on a date, they would tell their friends they are doing something else separately. Also, they could be careful about leaving any evidence of their relationship, like not leaving love notes where their friends could find them.
One common theme is rivalry - turned - friendship. Their initial intense rivalry in the original story often forms the basis, and fanfics explore how it can transform into a deeper bond. For example, they might start to train together and realize they can learn a lot from each other.
Well, there's a fanfiction called 'Izuku and Female Katsuki: The Unlikely Pair'. In this story, they start off as rivals but gradually develop feelings for each other. It has some really interesting character development. There's also 'Love in the Midst of Chaos' which is set in an alternate universe where they have to team up more often and that leads to a romantic relationship.
One possible plotline could be Izuku having superhuman abilities that are not like the normal quirks in the original story. For example, he might have the ability to manipulate time or space in ways that are completely unheard of in the My Hero Academia universe. This could lead to him being both feared and revered by others.
One possible plotline could be Izuku using his knowledge of Pokemon to help him in his hero training. For example, he might study how Pokemon use their unique abilities and apply similar strategies in combat against villains.
A possible plotline could also be that they have a near - discovery moment. For example, someone on the team almost stumbles upon a clue that they are in a relationship, like finding a special gift Tony gave Ziva. This would create a lot of suspense as they try to cover it up and keep their secret safe.
